WATER-CLOSET. Y f

SPECILFIOATIOJV'` forming part of Letters Patent No. 284,544, dated September 4, 1883. Y Application led January 17, 1883. (No model.)

` To all whom it may concern,.-

Be it known that I, OTHNIEL B. EVANS, a

citizen of the United States, residing inthe city and 'county of l Philadelphia, State of `Pennsylvania, have invented a new anduseful Improvement in Water-Closets, which im,-

provement is fully set forth in the yfollowing specification and accompanying drawings, in which- Figure 1 is a top view of the portion of a water-closet embodying my invention. Fig. 2 is a side elevation thereof. Fig. 3 is aver'- tical section of a detached portion thereof.

Similar letters of reference indicate corresponding parts in the Several figures.`

My invention consists of means, substanf tially as hereinafter Set forth, whereby the valve of a water-closet may be quickly and y easily opened and closed andheld tightly closed, provision being made for causing the.

valve to conform toany inequalities of the valve-seat. Y y

It also consists of `the construction ofthe joint of the collar and valve-chamber, said collar supporting the bowl and being support-4 ed on the valve-chamber, whereby escape of sewer-gas orvapors at said joint is prevented, said construction being` hereinafter fully described. l

Referring to the drawings, A represents a chamber, which is properly supported` on a `the chamber A, and provided with ears a, to

which is pivotedan arm, C, which is keyed or otherwise secured to ahorizontally-arranged rotary shaft, D, whose bearings are on the sides of said chamber, said valve having its seat on the bottom of the collar B.

To one end of the shaft D is secured a spurwheel, E, and with thesamemeshes a toothed segment, F,whose bearings are uprights, ears, or other suitable devices, those shown in the present case being uprights G; and said segment has secured to or formed with it a weight ed arm, 4H, to which is pivoted the handle or operating-lever J. (Shown in dotted lines.)

It will be seen that when the arm H- is raised the segment F moves downwardly, thus rotatingthe wheel E, whereby the con! nected shaft D lowers andopens the valve C, whereby there is communication between the bowl and place of discharge. Whenfthe rod J is let go, the weighted arm H immediately restores the segment F to its normal position, in which operation said rsegment moves in an upward direction and rotates the `wheel E, whereby the valve C` is returned toits seat, thus closing the communication between the bowl and place of discharge, it being seen that the weighted arm H now causes the valve to press rmly and continuously on its seat, thus producing` a tight joint between the parts, the valve, owing to its hinged connection with the arm C', readily conforming to any inequality of the face ,of the valve-seat. k

It is evident that the wheel E may be of the form of a segment, and both wheel or segment E and segment F may be beveled,l or of other suitable construction, the diameter of the wheel or segment E being less than that of the segment F, so that the motion of the valve in either direction is rapid, and the operation of opening the same accomplished with ease.

The top of the chamber A is flanged, as at o a, 4and the collar B has the lower portion,

which constitutes the seat, of reduced diam!` eter, so as to be readily fitted into said chamber through its flanged top, the reduction or contraction of said chamber forming the shoul der or sustaining-seat b, which rests on the flange c. Packing c is interposed between the shoulder and ange, and screws or bolts d are passed through Said shoulder and fiange,wherebythe collar "andchamber are securely connected, and the packing is rmly compressed on Athe flange as a seat, thus providing a tight joint between'the collar and chamber, through which the sewergas and vapors are prevented from escaping.

It will alsobe seen that the upper face of the shoulder b of the collar B supports the bowl, and the lower face thereof provides the surface for supporting the collar on the top of the chamber, it being noticed that the top,"

bottom, and intermediate bend are of one piece of metal or material.

When it is required to reach the valve C, the .shaft D, or the interior of the chamber A, 5 the screws or bolts d are loosened, and the collar B may be raised from the chamber and entirely removed therefrom, thus exposing the valve, and permitting; access to said valve and the chamber and other parts thereof, by which ro provision also the setting up of the valve and connections within the chamber may be readily accomplished.

In order that the chamber A may be sufficiently large at the side occupied by the shaft i 5 D to permit the motions of the valve C and valve C without the necessity of widening said chamber, the flange a is turned inwardly, it being noticed that the flange a is turned outwardly, the two flanges firmly sustaining the collar B, the packing c being interposed between said sustaining-seat b and top of the chamber, as has been stated.

As the valve is adjusted by the weighted arm to .hold a certain amount of water within the bowl as a seal, should water leak into the bowl the valve will drop, then discharge the surplus, and immediately afterward automatically close and tightly scat itself. In the event of back pressure of water, Src., within the chamber A, the valve cannot open, and thus overflow of the bowl and escape of vapor, 1&0.,

- therethrough is prevented.

Having thus described my invention, what I claim. as new, and desire to secure by Letters 3 5 Patent, ilsl. A chamber and valve-seat, in combination with a valve, C, and arm C', rotating shaft D, gear-wheel E, and the toothed segment F, having a -weighted arm, H, said valve being pivoted to said arm, substantially as and for the purpose set forth.

2. A bowl-supporting collar provided with a valve-seat, and a discharge-chamber sustaining said collar, which projects thereinto, in v combination with a valve, an operating-arm hinged to said valve, a rotating shaft connected with said arm, gearing E F, weighted arm I-I, and handle-lever J, the wheel E being of less diameter than the segment F, substantially as and for the purpose set forth. 5b

3. I n awater-closet, a chamber and avalveseat, in combination with avalve having ears a, the arm C, pivoted to said ears, the rotating shaft D, connected with said arm, the gearing E F, and weighted arm H, substantially as and for the purpose set forth. f 4. In a water-closet, a discharge-chamber with a iianged top, in combination with a bowl-supporting collar having a contracted part forming at its bottom a valve-seat, and 6o above the same a bend or part forming a sustaining-seat for said collar on the'chamber, the upper face of said bend sustaining the bowl, substantially as and for the purpose set forth.

5. In a water-closet, a valve, valve-seat, and 6 5 an arm and rotary shaft connected with said valve, in combination with a bowl-supporting collar, and a discharge-chamber which supports said collar, having at top an outwardlyprojecting flange, a', and an inwardly-project- 7o ing flange, a, substantially as and for the purpose set forth.

6. In alwater-closet, a valve, lvalve-seat, and an arm and rotary shaft connected with said valve, in combination with a bowl-supporting collar, having a contracted part forming at bottom said valve-seat, and above the same a bend or part forming a sustaining-seat, and a discharge-chamber, which sustains said collar, contains the valve, and is formed at top with a fiange, on which the sustaining-seat of the collar is rested, packing being interposed between said fiange and seat, the upper face of said bend sustaining the bowl, substantially as and for the purpose set forth.
